Sloping floor in loft conversion

Hello

I'm currently renting a house which was advertised as a 3 bed and has a loft conversion.

I've noticed that the floor in the loft slopes, almost from the middle, down to the front and down to the back of the house. The slope begins directly above an internal wall on the 1st floor, with this being the highest point. There is a gap at either end of the attic of about 1 inch between the skirting board and the floor, which I think hasn't always been there but can't be sure.

The landlord has told us it's just the way it is and so my question is is this something I should be pushing him more on? We're also looking to buy the house from him in future - would this come up in a building survey?

And my other almost related question - the council has records from only 2000 of all projects with building regs. This conversion doesn't appear so was likely done before. What are the rules around this? It's still able to be advertised as a 3 bed without the regs? I though regs started before 2000 so what's the deal with conversions done before this date?

Thanks in advance - and be as patronising as you like - I know nothing!!!

Well I can't see your pictures unfortunately but they generally build floors level so yes it is a concern.

I haven't got any pictures. Not sure what you'd want pictures of? We can't take the floor up as it's a rental as previously stated.

As a tenant, you have no right to a level loft floor.
